Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, and in particular to a hand rehabilitation training glove for stroke patients. Background Art

[0002] Stroke, commonly known as stroke, is a disease caused by various reasons that damage cerebral blood vessels, resulting in focal or global brain tissue damage; it is mainly divided into: ischemic stroke and hemorrhagic stroke; common symptoms of stroke patients include: dizziness, language dysfunction, vertigo, limb numbness or movement restriction;

[0003] Patients with limb numbness and restricted movement are particularly seriously affected by the disease. Mild symptoms only limit limb movement and do not follow the brainstem's instructions. Continuous development will cause fibrosis of the hand muscles, continuous shortening of the muscles, tendons and other soft tissues around the joints, and cause pathological disabilities such as joint twisting and deformation.

[0004] Therefore, many types of hand rehabilitation training devices are produced in clinical practice. However, the hand training devices in the prior art only mechanically drive the human hand to perform reciprocating motion when performing rehabilitation training on the finger part, but cannot perform impedance training on the hand, and it is difficult to adjust the training course according to the finger rehabilitation status during the training process;

[0005] In addition, existing hand rehabilitation training devices only train the fingers, but ignore the fact that the wrist is also a key affected area of ​​muscle fibrosis. Therefore, if there is a lack of rehabilitation training for the wrist, only the fingers are trained, and the muscle fibrosis of the wrist is not only limited in wrist movement, but also affects the normal movement of the fingers to a certain extent.

[0006] In summary, the hand rehabilitation training device in the prior art has the following problems:

[0007] 1.
